Description: Network design, signal processing, and control algorithms for industrial wireless sensor networks, and their implementation on off-the-shelf platforms. Specific application domains were the power industry and intelligent transportation systems. The outcomes of the project were: (i) SmartConnect: a system for design and deployment of multihop wireless networks for sensor interconnection. (ii) Dynamic control algorithms for traffic lights. (iii) Algorithms for vehicle detection and counting using road-embedded magnetometers.

Description: The broad area of research was wireless communication and networking. The systems we have worked on include multihop ad hoc wireless networks, both static and mobile, as well as cellular networks. A considerable amount of progress was been made in the application of noncooperative game models in the context of wireless cellular systems. There were also contributions to the area of network neutrality in the context of the wireline Internet. Stochastic control techniques were been applied to forwarding problems arising in delay tolerant networking (mobile opportunistic networks, and sensor networks with sleep-wake cycling). We used continuum or fluid limits in several problems of analysis and design of mobile opportunistic networks; in addition we contributed to the theory of such limits as well.

Description: Our Phase 1 work on developing a Wireless LAN Manager evolved into ADWISER a centralized performance management system for heterogeneous enterprise networks comprising an Ethernet LAN, a WLAN, and an Internet access link. ADWISER has been developed on a Linux platform, and utilizes centralized coarse-time sliced scheduling to manage the performance of multi-AP wireless local area networks and the enterprise Internet access link.

Description: The objective of the project has been to develop network design techniques and health monitoring sensors for hospital-based wireless sensor networks for the on-line monitoring of mobile patients.

Description: The objective is to set up a PIR-sensor based WSN to detect and report unauthorized entry in the vicinity of a sensitive installation, while seeking to minimize the number of false alarms arising due to environmental factors. Intrusions will be reported to a nearby building via a Wi-Fi or multihop network. A WSN will be set up to monitor human traffic across the entrance of two rooms within a building.

Description: The aim of the project is to design coding schemes for efficient and reliable storage of data in two types of storage technologies: (a) magnetic recording and (b) flash memory, used in USB pen drives, for example. The coding problems considered in the magnetic recording part of the project pertain mainly to one-dimensional (1-D) probabilistic and combinatorial models of the storage channel.

Description: The aim of the project is to develop secure multiparty computation protocols that can be implemented to secure efficiently the communications among an aribtrary group of autonomous computing nodes, such as smart mobile-phones, possibly assuming a semi-trusted central (cloud) facility. The semi-trusted central facility is not trusted to possess the group's secrets, but is only trusted to the extent of delivering messages to the intended parties as expected by the entities in the group, and to be a trustworthy source of randomness.
